Conservation of Mass?

Ok. This week, all I can remember seriously learning was the conservation of mass, and a bit about alpha, beta, and gamma decay. And we talked a bit about nuclear fission and fusion. Then, the next thing I hear is that we have a Test on Monday! WHAT!? Oh no! What have we actually seriously learned. Gosh, I don't know what to do! Seriously, WHAT HAVE WE LEARNED? Well, wish me luck! :(

Spreading Sheets

It's my 9th week of school, and I learned how to make a spreadsheet on Google Docs. We did a lab about half lifes, flipping 100 pennies in three trials. Within 6 flips, we would end up with 1 or 2 pennies on tails. Amazing isn't it? After finding our data, we made our spreadsheets on Google Docs. That was a pain, because I had no idea how to use it! Thankfully I learned, and I made a really cool chart with the spreadsheet and it was cool! I hope I get to do more of it!
